I'm trying to understand the difference between those 3 amps and how they relate to the AB763 circuit. For example, is the deluxe reverb a 22w version of a twin? Princeton, a 14w version? Enlighten me! Thanks
The Princeton Reverb is not AB763. It has a different phase inverter, amongst other differences. It's tone stack, though, is the same as the AB763's. It also different tremelo circuit than the AB763 amplifiers.
The Deluxe reverb and twin reverb are closer to each other. But, again there are differences, the deluxe reverb is tube-rectifed, whilest the twin reverb is diode-rectified. The deluxe reverb is brite (it's "brite cap" is always "on" so to speak), the twin has an adjustable mid range, and of course, the twin has 4 6L6 output tubes, much larger transformers, 4ohm output Z, and two speakers.
The Princeton Reverb is not AB763. If has a different phase inverter, amongst other differences. It's tone stack, though, is the same as the AB763's. It also different tremelo circuit than the AB763 amplifiers.
